National Coming Out Day (NCOD) is an annual civil awareness day internationally observed on October 11.

Founded in 1988, in the feminist and gay liberation spirit of the personal being political, the emphasis is that the most basic form of activism is coming out to family, friends and colleagues, and living life as an openly lesbian or gay person.

The foundational belief is that homophobia thrives in an atmosphere of silence and ignorance, and that once people know that they have loved ones who are lesbian or gay, they are far less likely to maintain homophobic or oppressive views. The process of coming out involves self-disclosure of one's sexual orientation and/or gender identity.
